= There is one bus cycle for byte and word operands and two bus cycles for long

operands. For long bus cycles, add two clocks to the tail and to the number of

cycles.

∗= Each bus cycle may take up to four clocks without increasing total execution time.

= Control registers USP, VBR, SFC, and DFC

= Number of registers to transfer

= Register List

<= Maximum time (certain data or mode combinations may execute faster).

NOTE:

The MOVES instruction has an additional save step which other instructions do not

have. To calculate the total instruction time, calculate the save, the EA, and the

operation execution times, and combine in the order listed, using the equations

given in 5.7.1.6 Instruction Execution Time Calculation.

5.7.3.5 ARITHMETIC/LOGIC INSTRUCTIONS. The arithmetic/logic instruction table

indicates the number of clock periods needed to perform the specified arithmetic/logical

instruction using the specified addressing mode. Footnotes indicate when to account for

the appropriate EA times. The total number of clock cycles is outside the parentheses.
